Service-Smart Shade Trees: Choosing Species & Spacing for Tea Producers in Northern Laos

This research brief reveals how smart shade design can make Lao tea farms more productive and resilient. Across nine plots in Xieng Khouang, results show that trees shape everything: yield dips close to trunks, but tea quality and soil protection soar under moderate shade. Not all trees are equal, Mak-Kho (Livistonia speciosa) stands out as a top performer. The takeaway: space trees 3-6 m apart and choose service-rich species for better cups and safer soils.
